It is in side the trans on top of the valve body. Why do you think you need to replace it?

I recently had the same issue, but my airbag warning lights also turned on. If this is the case, it might be the clockspring. There is a recall on clocksprings for Caravans 1998 - 2000 I believe. I got it replaced for free in the dealership. Enter your VIN in this site and it will tell you if you are covered in the free replacement warranty.

Under the hood. Under the cover for the fuse box is a map of locations

This maybe a problem of the hood being misaligned. in order to remedy this you will have to adjust the 4 bolts on the hinges holding the hood in place and the latch little by little. But first try a penetrating oil on the latch assembly and look for anything out of place.
